    I would use the Digi XBee3™ Cellular LTE-M Development Kit to create a GPS tracker.  I have another board I would like to connect to a cellular network. The board allows me to get GPS data and store it on an sd card but I would like to take that data and upload to a cloud database where I can use something like google maps to see where the device is at anytime.  The idea for this is to ultimately create a device that can be used for automatic check-ins at checkpoints for a city wide scavenger hunt game.

  • Zvonimir Siljic 2019-02-22

    I would use the Digi XBee3 development board to integer it on a remote operate vehicle ROV. and use it for telemetry.  The main function of this underwater vehicle will be get investigation data. For example Mark in maps seabed with poseidonia or other kind of natural species that should be protected. Or areas with plastic waste that should be cleaned.

  • Mark Renfro 2019-02-22

    I would use the Digi XBee3™ Cellular LTE-M Development Kit to build a pet tracking device. The unit would use gps to
    relay position data over cellular to help locate a lost pet as well as give an initial alert if the animal leaves it’s preset geo-fence boundary location.

  • Cris Thomas 2019-02-23

    In Kerala (India), the energy consumption is monitored and calculated by frequent field visits by technicians from the electricity/energy department for the calculation of energy fare which is a time-consuming task as there will be thousands of houses in the area. There is no provision to check or analyze the individual energy consumption of houses in a period of time nor to create a report of energy flow in a certain area. This is not just the case of Kerala, but throughout many places in the world. I am proposing a smart energy monitoring system with the help of Digi XBee3 cellular LTE-M module (from Development kit) to ease the inspection, monitoring, analysis, and calculation of energy fare. The system by constantly uploading energy consumption data (using an unique user ID) to a cloud data base with the help of the LTE and cloud connectivity of the device. It will additionally allow generating user specific or area specific charts and reports to analyze the energy consumption and energy flow of an individual house or a region.

  • szabraham 2019-02-23

    I would use de Digi Xbee3 Cellular LTE-M Kit to build a remote farm monitoring system, for use in spaces where is no landline internet access. The module would be a perfect solution as it can send an SMS to the owner with status updates and alerts, where internet access on the phone is no option. The system would monitor the health of the crops periodically, the moisture level of the soil, the air quality/temperature in the barn, the levels of water, and the feeding system, control the irrigation system etc.. The Xbee3 module would be used to do the communication between locations and with the central server for data transmission and alerting system.

    With an ever increase in the number of vehicles and the absence of a proper system to monitor and manage the traffic is a widespread issue throughout every country. Existing solutions like vehicle GPS tracker are vehicle and area specific. They are not capable of providing advanced traffic management and analysis. I propose to build an intelligent Traffic Evaluation, Management and Monitoring system that is capable of relaying the real-time vehicle and user data and vehicle location into a dedicated cloud for advanced analysis. This allows transport providers to manage their fleet efficiently. The Digi XBee3 cellular LTE-M module will be made as a standalone compact solution that can be incorporated into any vehicle and linked to a specific user identification number. Once the system is activated, it starts to stream real-time vehicle data and location into the dedicated cloud server. At the cloud server, this data is accumulated and processed by intelligent machine learning algorithms for analysis and monitoring on traffic flow, traffic volume prediction (expected traffic at a particular place at a particular time), real-time traffic density along a route, vehicle theft monitoring, fleet management, public transport monitoring, vehicle tracking, intelligent pooling etc.

  • Martin_Petrei 2019-02-24

    I would use the Digi XBee3™ Cellular LTE-M Development Kit to create a GPS tracker. This device will be associated with people with mental disorders (such as Alzheimer’s).
    It is a device that is in sleep mode until it receives an activation message. After being activated, it sends the current location periodically. The idea is that, in case the person is lost or disoriented, another (or other) persons may require information on their whereabouts.
    Two possible upgrades to the device are: add an “anti panic button” so that in case the lost person becomes aware of their situation, they can request help; add a heart rate sensor to know, in addition to the location, the state of health.

  • Martin_Petrei 2019-02-24

    I would use the Digi XBee3™ Cellular LTE-M Development Kit to create a device associated with a series of sensors: acceleration, temperature and humidity. This device will also have location information through GPS.
    The idea is to use it to monitor the condition of a fragile or sensitive load during its ground transportation. The data collected can be consulted in real time, with record of minimums and maximums to determine if at any point of the journey the merchandise transported was under unacceptable conditions.
    As an addition, the device could be provided with an interface that allows adjustment of alarm levels, so that in case of activation of one of these alarms a warning is sent, indicating the position and the reason for the alarm.
    Similarly, an interested user could send a message to the device to inquire about the current status, obtaining the location, current values of temperature and humidity and average of the latest records.

  • Martin_Petrei 2019-02-24

    I would use the Digi XBee3™ Cellular LTE-M Development Kit to create a device that allows to monitor land transport, whether merchandise or people.
    The idea is to provide information in real time and records of the entire journey, about basic parameters, such as fuel level, geographical location and vehicle speed.
    Using an accelerometer could generate a record of abrupt maneuvers (turns, braking, etc.), which helps to evaluate the efficiency of the driver of the vehicle. By increasing the complexity of the device, it would be possible to have sensors for water temperature, for example, or some other parameter of interest about the operation of the vehicle.
    All this information would be available in real time, with the ability to generate alarms or even the possibility of sending a message requesting help from the vehicle.

  • paviWeirdo 2019-02-24

    I would use the Digi Xbee3 cellular LTE development kit to create a health monitoring assistant for people suffering from back pains. It will help the doctor to monitor the posture of the patients suffering from back pains and the stress to which they are subjected to helping in fast recovery. The data collected from the sensors will be transported to a database in the cloud for processing and analysing the data. Further, the assistance will send SMS alerts and notifications to patients regarding their treatment, posture, appointment remainder etc., A 24x7 monitor to help the doctors and patients for a quick recovery is the aim of this project.

  • skorav 2019-02-24

    I’d use the Digi XBee3™ Cellular LTE-M Development Kit to extend my home automation with the cellular connectivity and to extend the range for my wireless sensors and actuators. Especially it would be great for the security system with two way audio and visual communication.

  • Chukman 2019-03-01

    Following e-bike mobility issues, security is a major hurdle to overcome.
    A modular solution makes sense if you also want to measure key parameters and offer real time updates.

    I would like to use some Arduino magic, a GPS module and the proposed majestic Cellular LTE-M Development Kit to develop a simple real time e-bike monitor.

    I hope to further complete this mobile information solution by adding a bunch of sensors to it: an accelerometer, a revolutions counter (speedometer), a temperature sensor, a grip skin conductivity sensor (handlebar), a PPG sensor (handlebar; heart rate), humidity etc

    Data would be routed to a cloud service like Thingspeak then processed and stored.

    A well thought equipment enclosure is a must too: bit of CAD wizardry, few 3D prints and that should be sorted fast - not forgetting waterproofing.

    Dabbling in power solutions… this system could use a step down for onboard battery power or use it’s own power source: potentially solar powered with a Li-Po pack. Hassle free use, low maintenance device is what I hope to end up with that solves the problem described at the beginning.

    The health of bee colonies is a critical situation in agriculture. Mostly, however, the beehives are far away from power supply and communication options. At the moment, the only way is to use a cellular connection.
    The monitoring of a beehive is not a big requirement. Usual and widespread sensors for temperature and humidity measurement in combination with acoustic monitoring by means of microphones are sufficient in a first step for a low cost solution.
    The Digi XBee3 cellular LTE-M embedded modem with its long battery life time together with a low power microcontroller is ideally suited for this task.

  • adsicks 2019-03-01

    I would use the XBee3 Cellular Development Kit to monitor machine that I manage at a commercial laundry mat that uses the Easy Card system. It would be nice to have a secure path to send troubleshooting data to the cloud and into the Self-service Asset Management InSite system I am developing.

    In our busy modern life, it is easy to forget small details during the day. One of these details is to lock your car after parking it. For most of us it is an automatic action we make without paying attention or remembering it later. However, after entering in shopping mall/stadium/theater, etc. we might be hit by the doubt if we did it or not. In my project, an embedded system based on Digi XBee3™ Cellular LTE-M Development Kits is connected to the car alarm system and therefore the car alarm status (locked/unlocked/sounding) can be checked online using a mobile app as long as the Internet is available. Therefore, the car’s owner can have some peace of mind and enjoy the rest of his day. A secondary advantage of this embedded system is its ability to automatically warn the car’s owner if the alarm sounds. This feature is especially useful to prevent draining the battery, robbery and also to avoid fines/car being towed away if it was left with the alarm sounding near a hospital or nursing home. The project might be further extended to perform real-time tracking if a GPS board is used.

  • lordninja 2019-03-12

    I would utilize these to create a simple sensor system that would send a simple series of haptic pulses to a wearable (Bracelet/pin?/smartwatch?) device letting people or a person know that a door was opened or perhaps the fridge/cabinet. This would be great for blind/deaf folks and others beyond allowing for fairly discreet alerts. I would focus on ease of use and mount-ability.  I am capable for writing a little app for this for the implementation and would be honored to do so! Thanks for reading.

    I would use the Digi XBee3™ Cellular LTE-M Development Kit to create a flood water disaster warning system. I called it IoFloodBeacon. The system will have multiple sensors such as ultrasonic water level sensor, temperature, humidity sensors, rain detector and rain gauge, atmospheric pressure sensor and light intensity sensor, wind speed and wind direction sensor. All the sensors will collect the environment and weather related data and pass those to control center using the Digi XBee3™ Cellular LTE-M embedded modem. The system will be battery powered and battery will be charging through a solar panel. So the device can be place any remote location water reservoirs (river, tank, lake, etc.). I will create an android mobile, web interface and rest API then retrieve data from the control center then convey the information such that whether river or lake about to overflow or not to public and save their lives from the disaster. Furthermore I will develop this system to predict the disaster before it happened then I can save more people and properties from the flood water. This system will be served other disaster situation too such as land sliding.

  • xxnofearxx22 2019-03-13

    My team and I are currently developing a small Quadcopter drone that integrates LiDAR distance sensing with cross-platform communication systems that utilize LED lights as efficient methods of inter-nodal communication. Each drone represents a data node in a network and the key idea is to securely transfer data from point to another through the use of optical links. While the optical link process provides secure communications, the primary data transfer point from the user to the first drone will be realized by using some form of data transmission utilizing radio frequency.  I would use the kit described above to act as the primary link from the user to the first drone, allowing for the propagation of the data to the network. This data would consist mostly of commands given to the decentralized command and control modules to transmit to a specific target with an optical link. A further use would be to provide more accurate GPS data so that the transmission link for the drone targeting system would have increased accuracy, increasing data transmission rates.

    The proposed project will use a Digi XBee3™ NBIOT Cellular Development Kit to build a hay moisture monitoring solution for farmers. If you’re a farmer you know that humidity , dew-point and hay moisture are critical for proper baling. The right humidity is needed for cranking up the combines for wheat harvest in summer or the cotton stripper in fall. High humidity and mild temperatures make it ideal for fungi to attack plants. Low humidity increases fire danger.

    The solution will use a Si7020 MEMS humidity sensor to build a network of humidity edge nodes that transmit to a central device (Raspberry Pi). The data will be displayed on a Grafana dashboard. An IFFT rule can be created that alerst when humidity is too low so that a notification can be sent.

    There is a huge problem with public transport monitoring and enforcement (leading to deaths). This applies to freight, human and special transport on the roads. The idea is to make a device - like a GPS tracker, with all the gyroscope and barometer, acelerometer etc components - and install it in fleet vehicles that are registered in the program - the devices records all the measurements on it. It can send the information to a central service to record information. BUT - add a security module to the device to allow the Traffic Law Enforcement agency / or any authenticated person to access the device via bluetooth / wifi to extract the information from the device (road side / office) - this information is then used by the enforcement agency for further processing - it can use GPS to see off-route / average speed etc

    I would use the Digi XBee3 to allow people to monitor a Smart Soccer ball during the events, streaming in real time statistics about the ball’s velocity, acceleration, trajectory, force of kick and distance traveled. For the past 4 years I have been developing a Smart Soccer ball called InsideCoach and I think the next step would be to build a wireless broadcasting device that would collect data from the ball as well as from wearable sensors on the players and allow anyone interested to view and create amazing things with this telemetry data. We are currently participating in a startup program that would allow this technology to featured during the world cup in 2022 world cup in Qatar.

    I have an elementary school project that the the Digi XBee3 NBIOT version (low power) would be perfect for. This year, my daughter’s school has been studying the Hudson River in upstate NY all year.  I’ve helped them setup a set of control experiments and we do some electronics with a USB microscope and sensors for a raspberry pi, along with taking measurements and plotting the year’s history of the river.

    That XBee cellular kit gave me an idea: I would love to end the school year with a 50+ mile journey of a toy boat the class would build.  A boat with a number of sensors and gps to highlight what the river is known for, “The River that Flows Two Ways.”  This XBee device would make it possible to not only relay all of that information back in real-time but to also tell us its position we can plot on a map.  Because one of the main issues is getting the boat back - especially if we don’t know where it is!

    The kids are already experienced boat builders (it’s one of their year end projects they have done a few years already).  I already have most of the sensors and I think an old GPS unit that will work.  Thinking about a servo as a “release” mechanism so we can do it remotely from the school when we are ready to track it live.  Of course, that service would be controlled via a reverse shell coming from the boat to my server, where I can login and execute the commands to release the servo.

    Thank you AAC for giving us a chance!  This is a great idea for a giveaway!

    Recycling is important to both the natural environment and us. We must act fast as the amount of waste we create is rapidly increasing, thereby damaging our planet.
    We would like to help the authorities to act efficiently towards waste collection. We propose a “Recycle bin garbage level monitoring device”. As it already emerge from the project title, the device would use some ultrasonic and weight sensors for monitoring and statistics.The bin’s current state would be visible through a mobile application for everyday users and a web platform for the City Halls. The product aims at a low-consumption and cost-reducing implementation.
    Of course, the key point and the most time-saving element would be announcing the authorities about waste-level through an online platform that would ensure a cellular connectivity. Collecting the trash when needed, keeping the environment clean and obtaining statistics should simplify and improve the recycling process.
    That’s why Digi XBee3 Cellular LTE-M Development Kit would integrate perfectly in this project. //14

    I would use the Cellular Xbee3 to create a safety and security system for a bicycle or motorcycle. A form fitting attachment containing the Xbee and all other electrical components would attach to the frame of the bicycle and lock, so that it could not be removed by anyone but the user. I would incorporate an accelerometer and GPS with the system, mainly so that speed and acceleration could by calculated. Using this data, the user could put the device in a security mode, and would receive a text message if the bike were to move (like it was being stolen). The user could ping the bike and it would report its GPS location. The safety feature would text an emergency contact if an extreme deceleration were detected. Basically, if the speed was over a certain limit and a deceleration of a certain amount was detected, then the system would go into alert mode and beep. If the bike was not moved (picked up, something) after some short amount of time, 20-30 seconds, then the system would text an emergency contact that a crash was detected, along with the GPS coordinates of the bike.

    IoT devices are becoming a very common devices in our day-to-day life for various application for House holds, smart cities, Agriculture, Education, Industries, Medical, etc for real-time monitoring and controlling. Agriculture is the major method to produce food for all, if the crop is grown in feasible conditions with proper watering gives good yields. Watering the plants and trees in farms is the major problem to protect them from starving and risk of patient to the farmer to monitor the water conditions hour to hour and their is also power crisis. I designed a Solar water pump system to overcome this issues but I am facing a problem to know the status of the solar water pump system and environmental parameters remotely due to short range Wifi data connectivity. In my current project, I would like to monitor the status of the Solar water pump system parameters and the environmental parameters using Digi International XBee3™ Narrowband IOT (NBIOT) Cellular Development Kit. This kit has 1) Extreme low power consumption for battery life: The device can run for long time which is very important for the agriculture devices. 2) Integrated MicroPython programmable: Ease to program and can connect multiple Hardware controller units and can access them with different protocols. 3) Cellular service: IoT enhance due to the cellular connectivity because the signal can reach to every corner of the location. 4) Excellent coverage and building penetration: Signal can be transfer to long range and into the closed rooms like farm house for data transmission. 5) Digi TrustFence: Designed for mission-critical applications, enables to easily integrate device security, device identity, and data privacy capabilities. The device will be more secure with this kind of features.
    I would like to add Digi International XBee3™ Narrowband IOT (NBIOT) Cellular Development Kit in our design so that the data from sensors like current, voltage, panel temperature, light intensity, air temperature, soil moisture, humidity, pressure, wind, day light duration can be transfer remotely and can store in cloud for future processing. The data can help the Government to know the utility of solar energy for water pumping used for agriculture. Govt. can provide better subsidy for farmers if they are utilizing it in effective. The cellular connectivity will be available in any location so the data can monitor at any place by accessing in Cloud. I hope this device will be the suitable one for my design for Solar water pumping system for Agriculture.

    A good application for the Digi XBee3™ Cellular LTE-M Development Kit would be one that combines the advantages of the LTE Cat M1 and the NB1 networks. To achieve this, I propose a smart home security camera running on battery power. This camera would have a motion sensor which can notify the home owner of motions in his house over the low power LTE NB1 network. If the home owner thinks no one should be home and wants to check what is going on, he can activate the live stream which uses the higher bandwidth of the LTE Cat M1 network. This network will also be used to push software updates to the camera. With this system of smart network selection, we can achieve a long battery lifespan without removing the benefits of a fast network when it is actually needed. The main benefit of a security camera not using the local WLAN is of course that an intruder cannot simply turn off the power of the network.

    The Digi XBee3™ Narrowband IoT (NBIOT) Cellular Development Kit is used in my earlier project on Laboratory synthesis process monitoring. I would like to know the status of the process but my earlier design IoT device is limited to WiFi connectivity and it is difficult to get the data from the sensors because it has range limitations and data is not penetrated from the closed chamber. Digi XBee3™ Narrowband IoT (NBIOT) Cellular Development Kit is low power consumption, MicroPython programung, excellent coverage and building penetration, Digi TrustFence and cellular service so this kit is easily fit in my project to monitor the status of the processing unit. It will be a good opportunity for me to update my existing system and connect it over cellular service for data transfer and monitoring.

    Instrumentation and data acquisition (DAQ) in research facilities involves a lot of wiring, which introduces many complications such as noise pickup, complex wiring, lack of space, cost of installation, safety, and the physical difficulty of debugging sources of error. Often, the central DAQ unit cannot be placed near the instrument, and must instead be connected with meters of cables. Furthermore, often these data streams are for “housekeeping” purposes as opposed to critical synchronous data acquisition, i.e. to ensure the facility is operating within normal parameters. These difficulties can be minimised by reducing the amount of wiring required in such installations. Data acquisition and analogue-to-digital conversion (ADC) can take place close to the instrumentation, and data can be read asynchronously via wireless provided by the Digi XBee3. If each instrument is connected to local hubs with the Digi XBee3, the entire facility can essentially be monitored from a single DAQ unit at any location without the hassle of cables. (You can probably tell I really hate cables)

    Climate influences the distribution of crops over different regions of the world while weather influences crop production and productivity. So,me and my colleague hope to make a smaller weather station that will determine the values of soil moisture, wind speed, precipitation, soil temperature for productivity favorable to farmers. Temperature influences distribution of crop plants and vegetation. It affects leaf production, expansion and flowering. Wind causes soil erosion,heavy wind damages crops like banana, sugarcane. It spread of pest and diseases,that we can avoid with our system. High humidity can prolong survival of crops under moisture stress but will reduce the yield. Rainfall plays important role in life processes by gas exchange (1 cm rain over one hectare is 100m3 (1, 00,000 lit) contains 4,339 gms of O2 = 3000 lines of pure O2.) Quantity and distribution of rainfall decides the vegetation of an area.
    Using the Digi XBee3™ Cellular LTE-M Development Kit would have several advantages including:
    1)low energy consumption optimized for a long battery life which is very important to put into practice our idea,2)integrated MicroPython programmability,MicroPython includes modules such as “machine” for accessing low level hardware. MicroPython is packed with advanced features such as arbitrary precision integers, generators, exception handling and more.3)Enhanced with Digi TrustFence security framework, this will make the system safe and secure.4)Reduced hardware complexity with only 1 antenna required(very useful). We would like to add the kit development to our system as soil temperature, soil humidity, wind direction, wind speed, precipitation be transferred remotely and can be stored in the cloud for later processing.

    I would use the Digi XBee3 Cellular LTE-M Development Kit to act as a gateway between a mesh of Arduinos (probably Attiny85 as well) interconnected via 2.4ghz RF technology with the NRF24L01 board, and external services for emergency cases diagnosis. The idea is to place sensors all across a venue, shopping, or building, which send to main Digi XBee3 acting like buffers & dispatchers of this sensor data. Whenever the system detects a fire or gas escape, it turns into emergency mode. And that means, we send the last amount of buffered data to a main central of emergency, as well as we start sending realtime information of the place. So in case they need to figure out where the source issue is located, or which access are blocked, or where there is still people in the building, they can utilize that data to perform a more precise emergency plan.
